[QUOTE="Ivan Beaver, post: 59316, member: 30"] Re: Subwoofer comparison SRX728 vs Vertec 4883 Was that graph with or without processing applied? If you only see the processed graph-then you have no idea what the raw response of the cabinet is-especially down low. It is VERY common these days for manufacturers to put a boost down low to make the cabinet appear to go lower. yes it can do that-at the lower levels-HOWEVER-if you turn the cabinet up, whatever boost you have applied (often 6dB or more) HAS to be subtracted from the max output (at the freq it is applied)-because the driver simply can't handle it. And then the whole "1 watt thing" goes out the window-as they are no longer appling 1 watt to the cabinet for the graph. I have no idea which way is which-but the previous graph say 'processed"-so that really doesn't say a whole lot. I like the way EAW does on a lot of cabinets (sadly not all). They show you the unprocessed response-the processors response (where you can easily see the bossts that may be applied) and the final result. With the unprocessed graph-you gan get a better idea of the cabinet is actually capable of doing-especially when turned up. This gives way more information than a simple processed response. I would HOPE that a processed response is pretty flat-if not-something is wrong. Of course HF boosts are also common-but most people don't seem to care about that as much. But that can also add additional heating to the voice coil-and additional distortion because you are asking the driver to do something it can't-at least easily. And the HF boosts aren't as likely to cause damage (at least as much as the low freq boosts) from overexcursion or overheating. [/QUOTE]
